I think of the resource as a container that has certain capabilities. An
early use case for delegation was for access to Flickr photos. Write access
to upload new photos was a capability.

An example of a resource without an API is where the client is also the
resource, and has delegated authorization to the AS. For example, you can
imagine a photo copier where you scan a QR code that send you to an AS that
then returns an artifact to the client how the user is authorized to use
the photo copier.
